Windshield ice scraper

ABSTRACT

A windshield ice scraper in the form of a relatively flat box open at one end and having an oblique wall at its opposite end. The oblique wall and one of the flat walls of the box structure form a chisel-like scraping edge and the oblique wall has surface projections forming a rasp surface for scraping tenacious ice from a windshield. The user inserts his fingers in the open end of the box for using either the chisel edge or the rasp surface, the box being reversed in position in changing from one to the other.

A TTOPNEVS wmnsnnau) ICE SCRAPER BACKGROUND OF THE INVENTION This invention relates to scrapers for removing ice and sleet from vehicular Windshields and similar surfaces.

Windshield scrapers generally comprise a scraping blade with a handle projecting therefrom so that material scraped from the windshield is thrown back over the hand or glove of the user. Furthermore, conventional windshield scrapers rely solely on a chisel-like scraping blade for removing ice and the like from the windshield surface.

SUMMARY OF THE INVENTION The present invention provides a tool for removing ice or other frozen incrustations from Windshields and similar surfaces which is more effective, particularly in removing especially tenacious frozen coatings. The tool of the present invention provides a special rasp-like scraping surface for attacking ice formations of an unusually adherent or tenacious nature.

In addition, the tool of the present invention is of a generally flat boxlike formation so that either of the flat side wall portions may be used as the gripping surface with the hand and/or glove of the user extending into and protected by the boxlike formation. The device has an open end for thus gripping the same and the opposite end is oblique, preferably making an acute angle with one of the side walls to provide a chisel-like scraping edge.

The rasp-like surface comprises tooth projections on the oblique end surface so that the tool may merely be reversed to use either the rasp-like surface or the chisel-like formation. In either position the boxlike formation shrouds and protects the users hand. The boxlike formation further provides a rigid and sturdy structure without requiring excessive wall thicknesses.

The oblique end surface which forms the chisel-like scraping edge and contains the rasp-like protuberances inherently presents this rasp-likescraping surface at an optimum angle for convenient handling and for effectively exerting the required pressure for thorough and efficient scraping action.

BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a general elevational view of one form of the scraping tool of the present invention;

FIG. 2 is a side elevational view thereof; and

FIG. 3 is an end view taken from the right-hand end of FIGS. I and 2.

DESCRIPTION OF THE PREFERRED EMBODIMENT In the preferred embodiment the tool of the present invention comprises a unitary boxlike structure which is preferably of molded plastic of a relatively rigid nature. This boxlike structure comprises from and rear walls 10 and 11, side walls 12 and 13, and an oblique end wall 14.

End wall 14 extends at an acute angle to rear wall I I so as to form therewith a chisel-like edge adapted for windshield scraping purposes. The boxlike structure adjacent to this edge. that is the converging walls 11 and 14 and the adjoining side wall portions 12 and 13, render the chisel scraping portion of the device extremely rigid with relatively thin walls.

As clearly shown in FIGS. 1 and 2, the oblique wall 14 has a plurality of protuberances formed at its exterior surface to form a rasp-like scraping surface for acting against particularly tenacious ice formations or incrustations. The protuberances are designated 15 in FIGS. 1 and 2 and may be varied in size and distribution according to various design and utility requirements.

In employing the device for scraping purposes, whether the rasp-like protuberances 15 or the chisel-scraping edge are to be employed, the user places his fingers within the open end of the boxlike structure and grasps the front or rear wall with his thumb, depending on whether the protuberances 15 or the chisel-like edge is to be employed. In employing the rasp-like protuberances 15 the user may conveniently bear with hlS fingers directly against the interior of oblique wall 14 to conveniently apply effective scraping pressure.

A preferred embodiment of the present invention has been described and illustrated herein to illustrate the principles of the invention but it is to be understood that numerous modifications may be made without departing from the broad spirit and scope of the invention.

I claim:

1. In a hand tool for scraping ice or the like from a window or similar surface, a boxlike structure comprising a pair of spaced walls, side walls connecting said spaced walls to form a generally rectangular cross section, one end of said structure being open to receive the hand of the user, the other end of said structure comprising an obliquely disposed wall forming an acute angle with one of said spaced walls to provide a chisel-like scraping edge, and a plurality of relatively sharp projections at the exterior surface of said obliquely disposed wall to provide a rasp-like scraping surface.

2. A hand tool according to claim 1 wherein the boxlike structure comprises a rigid unitary structure.

3. A hand tool according to claim 1 wherein the boxlike structure comprises molded plastic material.

4. A hand tool according to claim 2 wherein the boxlike structure comprises a one-piece plastic molding.
